If the batteries die or you leave them on and forget(as I have done) They will function as regular ear protection but they will lose the ability to amplify regular sounds. Basically the best part about these is the ability to hold normal or even whispered conversation and hear really quiet noises such as twigs breaking or footsteps in the snow. To restate my answer they would be great ear pro even if they were dead- Chris
I have used these for mowing my lawn. I used my Apple iPod with a standard interconnect cable. The plugin on the headphones is the same as on the iPod. I was surprised how well they worked. I thought the volume would have to be very high but it was not. The sound protection was quite good and I could hear my music just fine. There does seem to be a limit as to how load you can adjust the music. I wanted it a little louder but found it to be quite adequate. It's rather surprising how you can turn up the volume and hear surrounding sounds better than without the headphones on. Then when start the mower, its sound is immediately blocked and I can now enjoy my music. I'm sure you'll like using them.
This by far one of the best and commonly seen at the range ear muff protectors. I have never had an issue with mine and love the slim profile they have compared to other models on the market. So, yes these definitely dampen the noise of every crack of gunshots far and near using a technology that dampens any noise over a certain decibel allowing you to hold conversations with others without yelling or taking if you ear protection. You can also use these with an mp3, iPhone, cellphone and listen to music if you'd like while shooting with the provided plug.
Ha! Funny you should ask because I have to change my battery also. If you look at your two ear pieces you will notice that half of one is half black and half green. That is where the batteries are located at. Gently, with your fingers, push up and that black cover should move and then lift it off. Once you are done make sure that you snap it back into place and that it is firmly secured.
These might work for that application, but I would try ear plugs first. Ear plugs would be cheaper, smaller, less distracting and less likely to fly off of your head when whipping your head around during an awesome dance move! Plus the ear plugs are disposable and you would have to clean the sweat out of the Impact ear muffs after each jazzercise class. The ear plugs would lower the overall sound of everything, but you would still be able to hear the music and instructor. http://www.amazon.com/Howard-Leight-Earplugs-Uncorded-NRR33/dp/B0013A0C0Y/ref=sr_1_1?s=hi&ie=UTF8&qid=1383340932&sr=1-1&keywords=howard+leight+ear+plugs
just my $.02. Good luck and keep on dancing!
I would think so. They are the most comfortable and quality functioning I have used by far. I have only used them on a range with my students but we can always talk and communicate comfortably. I have used them while mowing with the head phone jack and they were great as well. They can actually amplify normal volume levels while keeping out the harmful ones. I couldn't be happier with them. Two people have seen and used them and went and bought their own for the trap range now.
